Holland & Barrett Magnesium Bisglycinate

This product is a dietary supplement featuring Magnesium Bisglycinate, formulated as a stable amino acid-bound mineral. It is sold under the brand Holland & Barrett, which is a major wellness retailer originally founded in the United Kingdom in 1870 by William Holland and Alfred Barrett. Today, the brand is known for its extensive range of vitamins, minerals, and health foods.

While the brand maintains a strong retail presence in the Netherlands and Belgium (as indicated by the Dutch and French labeling on the packaging and the Amsterdam address), the high-level ownership and production standards align with its British heritage. The product is manufactured in the United Kingdom, following strict quality control standards for health supplements. Since 2017, Holland & Barrett has been owned by LetterOne, an international investment business that continues to expand the brand's footprint across Europe and globally.
